Brain stroke

Brain stroke happens when there is a blockage in the blood circulation in the brain or when a blood vessel in the brain leaks. The burst or blockage prevents blood and oxygen reaching the brain tissue. Without oxygen the tissues and cells in the brain are damaged and die in no time leading to many symptoms.

Once brain cells die, they generally do not regenerate and devastating damage may occur, sometimes resulting in physical, cognitive and mental disabilities.It is crucial that proper blood flow and oxygen be restored to the brain as soon as possible.

Types of brain stroke
Brain stroke is mainly two types.

Ischemic stroke: It is the most common type and contributes to 80% of brain strokes.
Hemorrhagic stroke: It contributes to 20% of brain strokes.
